Tikka T3 CTR 5 Round Magazine

Always recommend Beretta and their products...Customer svc. has always been great. Hoping for the same on this Tikka T3 CTR magazine. Unfortunately, the one I just purchased (5Rd) unseats & drops down a little, from the magazine well after each shot from the recoil, and will not chamber another round unless I shove magazine back up in order to chamber another round. Beretta immediately sent me a packing slip to send it back. They are quite pricey, but, extremely well built. I will try to purchase another one, now out of stock, of course, and hopefully it will work. Just have to take it out and waste some rounds through it to see if a new one they ship to me works. I have faith in Beretta....think this is a Tikka problem......Rifle is deadly accurate though. I will report later of hopeful success with a new magazine so I can give 5 star rating.
